// REMIND: Using an NSOpenGLPixelBuffer as the scratch surface has been
// problematic thus far (seeing garbage and flickering when switching
// between an NSView and the scratch surface), so the following enables
// an alternate codepath that uses a hidden NSWindow/NSView as the scratch
// surface, for the purposes of making a context current in certain
// situations. It appears that calling [NSOpenGLContext setView] too
// frequently contributes to the bad behavior, so we should try to avoid
// switching to the scratch surface whenever possible.
